Astudent reads in a science magazine that a mutation in a body cell causes it to divide rapidly, forming large masses of cells. these masses of cells cause other body cells to divide uncontrollably. the student claims that the mutation is beneficial to the organism. is the student's claim correct?

The mutation of a body cell that results in uncontrolled cell division and growth, which also results in the uncontrolled division of other body cells offers no benefit to an organism other than harm. The student's claim is INCORRECT.

Cells that do not stop growing and diving usually results to cell growth that is uncontrolled. This uncontrolled cell growth can form tumor which are detrimental to human health.

Cancerous cell behave the same say. Cancer cells usually arise after series of mutations in a body cell. Unlike normal cells, cancerous cell are non-specific, that is, they do not have a specific function they perform.

Thus, the uncontrolled growth of cancerous cell lead to formation of tumors and other unfavorable changes in the body of an organism.

Therefore, the mutation of a body cell that results in uncontrolled cell division and growth, which also results in the uncontrolled division of other body cells offers no benefit to an organism other than harm. The student's claim is INCORRECT.

The student claim is incorrect

Explanation:

Uncontrollable cell division leads to formation of tumours and cancers if cells were to lose contact inhibition and migrate to other parts of the body.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
